Introduction of High Pressure Flow Meter with Gear

Gear flow meter is a volumetric flow transmitter. A transmitter that measures volume flow with high precision. As the medium flows, the gears mesh and rotate. Under the action of the fluid flow, a pressure difference is formed at both ends of the inlet and outlet of the instrument. No power is required. A pair of gears rotate freely. The cavity between the gears is filled with liquid, and the liquid is discharged as it rotates. The number of revolutions of the gears can be measured to know the flow rate of the liquid flowing through the instrument.

We also customize PTFE flowmeters: PTFE gear flowmeter

What is a High Pressure Flow Meter?

High-pressure gear flow meters play an important role in various industries due to their high precision and high-pressure resistance.High-pressure flow meters specifically refer to flow meters with a pressure resistance higher than 4MPa. Conventional flow meters have a pressure resistance of 1.6MPa, 2.5MPa, and 4MPa. High-pressure flow meters can be customized to 10MPa, 15MPa, 20MPa, and 40MPa. They are commonly used in high-pressure water pipes, hydraulic systems, mud, cement slurry, high-pressure water injection, etc.

There are different types of high-pressure flow meters. Including volumetric, turbine, electromagnetic, gear, Coriolis mass flow meter, etc
